Ovulation occurs during the ovulatory phase of the menstrual cycle when an egg is released from the ovary.

The endometrium thickens during the luteal phase of the menstrual cycle in preparation for a potential pregnancy.

The average duration of a human menstrual cycle is approximately 28 days.

The corpus luteum primarily produces progesterone, which is essential for maintaining the uterine lining during early pregnancy.

The seminal vesicles produce a fluid that provides nutrients to sperm and helps form semen.

The acrosome contains enzymes that help the sperm penetrate the outer layers of the egg during fertilization.

The main purpose of the menstrual cycle is to prepare the female body for potential pregnancy each month.

The primary function of the male reproductive system is the production of sperm, which is essential for fertilization.

The ovary's primary role in the female reproductive system is the production of eggs (ova) which are necessary for reproduction.

Fertilization is the term used for the fusion of sperm and egg, leading to the formation of a zygote.

Testosterone is the hormone responsible for the development of secondary sexual characteristics in males, such as increased muscle mass and body hair.

Luteinizing hormone (LH) triggers ovulation, leading to the release of a mature egg from the ovary.

The menstrual cycle is a natural process and not a method of contraception.

The ovary is not a part of the male reproductive system; it is part of the female reproductive system.

The epididymis is the part of the male reproductive system that stores and matures sperm.

The ovaries are responsible for the production of eggs (ova) in the female reproductive system.

The ovaries are responsible for the release of eggs during the menstrual cycle.

The vas deferens is responsible for the transport of sperm from the epididymis to the ejaculatory duct.
